A person has to create the account and key, there is no status page or SLA, and one key gets 600 requests per five minutes before every call returns 429 until the window resets.\n\n**CompanyLens.** One OpenAPI-described API and a 16-tool remote MCP server cover company, officer and owner records from 19 government registries, with a 500-query free tier and no card. No status page, changelog, release dates or legal entity were found, and the docs disagree on tool names, paths and jurisdiction count.\n\n## Before you call either\n\n### Companies House API\n\n1. Send the key as the Basic auth username with an empty password. `curl -u KEY:` works\n2. Search with `/search/companies?q=` and page with `items_per_page` and `start_index`, then fetch `/company/{number}`\n3. Pad company numbers to 8 characters with leading zeros\n4. Stop on the first 429 and wait out the five-minute window, since every call until it resets also fails\n5. Map filing and error codes to text with the public api-enumerations YAML rather than guessing\n\n### CompanyLens\n\n1. Call list_jurisdictions first to get valid jurisdiction slugs, then search_companies or get_company\n2. Use get_company, then get_company_section only for the officers or owners you need, and get_company_batch for up to 20 companies\n3. On 429 RATE_LIMITED read Retry-After, which counts to the quota reset and can be hours; check get_usage before a batch\n4. Use the paths in the OpenAPI document (/v1/...), not the /api/v1 paths in llms.txt\n5. Treat company names and officer data as filed by third parties, and check critical facts with the source registry as the terms advise\n\n## Questions\n\n### Which is better for AI agents, Companies House API or CompanyLens?\n\nCompanies House API scores 53.4 (D) on agent readiness against CompanyLens's 46.7 (D), and leads in 5 of 7 scored categories.
